GENERAL INFORMATION
For numerous marine animals’ seaweed serves food and shelter. Seaweeds are a in a diverse group of living organisms living on the earths ocean .seaweed can be found in many places., You can find them attached to rocks in the inertial zone,. They can be very tiny, or quite large, growing up to 30 meters long!
SEAWEED STRUCTURE
Seaweed has holdfasts instead of roots which attach then to sea floor. The holdfasts are made up of many finger projections similar to halter. The stalk of a seaweed is named a stripe. This supports the plant. The stripe varies among different seaweeds. They can be flexible, solid, gas filled , short, and stiff. Blades are the leaves of seaweeds. The function of the blades is to provide a surface for sunlight. Thallus refers the entire body of the seaweed.
This shows the structure of the Seaweed
SEAWEED REPRODUCTION
. Some seaweed is living for many years, while others are called annuals because they live for only one year. Annual seaweeds generally start to form in the spring, and continue throughout the summer. During the strong fall and winter storms the stripes and blades will come off as the month progresses. New blades will grow if the stripes last during the strong winter.

Where can u find Seaweed
You can find seaweed in the inertial zone attached to rocks. Also u can find them washed up on the beach or floating on the oceans surface.
How big can Seaweeds get
Seaweeds can be really tiny or they can be large being about 30 meters.
This shows how long Seaweed can get.
Are seaweeds vascular plants
Seaweeds are not vascular plants. They are algae which are neither plants nor animals. Seaweed is not placed with the plants because they lack a vascular system. Since Seaweed is in contact with the water it can take up fluids, gases, and nutrients from the water.
Brown algae
Brown algae are found in different forms including crusts, filaments, and large kelps. Also they are a multi-cellular.
Green algae
Green algae are mostly found in the shallow inertial zone and warm tropical oceans. They are a part of the division Chlorophtyta group, which includes all green algae. 10% of marine species are green algae. The structure of green algae is from single-celled forms to multi-cellular sheets, and branched filaments. Red algae
The red algae are part of the Rhodophyta division. They are found in forms, like branched filaments, sheets, and fleshy plants. Some of the Seaweed are single celled when other seaweeds can have lengths of 2 or 3 meters.
